The maximum solid solubility of the transition metals in palladium

The maximum solid solubility limit (Cmax) of transition metals dissolved in palladium can be described as an equation in semi-empirical theories with parameters such as electronegativity difference, atomic diameter and covalent electrons. It has been found that the electronegativity difference and the covalent electron number mainly affected the Cmax of transition metals in palladium. The atomic size parameter had the smallest effect on the Cmax.
